LUBRICATOR FOR ELEVATORS.

SPECIFICATION forming vpart of Letters Patent N0. 437,351, dated September 30, 1890.

Application filed February 21, 1890. Serial No. 341,290. (No model.)

To all whom it may concern:

13e it known that I, J AMES M. ARNOLD, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators for Elevators, of which the following is hereby declared to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

In Letters Patent No. 398,695, granted to me February 26, 1889, is set forth a guide-lubricator for elevators comprising a cup that is bifurcated-that is to say, furnished with prongs or extensions to overlap or straddle the elevator-guide-the cup being provided with a suitable lubricant adapted to be forced against the guide.

The object of my present invention is to improve in sundry details the construction set forth in said prior Letters Patent, and this object I have accomplished by the novel features of construction hereinafter described, illustrated in the accompanyingdrawings', and particularly defined in the claims at the end of this specification.

Figure 1 is a perspective View of a portion of an elevator-guide and cross-beam, showing my improved lubricator attached thereto. Fig. 2 is a view in central vertical section through the cup orholder shown in Fig. l. Fig. 3 is a view in transverse section through the cup or holder shown in Figs. l and 2. Fig. 4 is a perspective View showing a modified form of my improved guide-lubricator. Fig. 5 is an enlarged view, in central vertical section, through the cup or holder shown in Fig. 4.. Fig. 6 is a view inrcentral vertical section through the back part of the cup or holder and the follower, showing a modified means for forcing forward the follower.

A designates one of the usual guides commonly employed in elevators, and B denotes the cross-beam at the top of the elevator cage or carriage, this cross-beam being furnished at each of its ends with a suitable slide C in well-known manner.

. Upon the top of the cross-beam Bis sustainedthe lubricant cup or holder D, this cup being shown in Fig. 1 of the drawings as carried by means of a bracket E, having a base e, that is adjustably held within a base plate or support F. This base plate or support F is by preference furnished with dovetailed ledges f, that serve tojsecure the base e' of the standard E while permitting it to be laterally adjusted, the vposition of the standard upon the base-plate being determined preferably, by means of a suitable set screw or screws e. -lWIy purpose in thus mounting the cup or holder D for the lubricant, so that it can be laterally adjusted, is to enable it toV be more readily and accurately positioned withrespect to the guides" of the elevator; and I wish it understood that while I have.

shown what I consider as a preferred means for so adj ustably sustaining the cup I still regard it as within the scope of my invention to mount this cup in any other convenient way which will permit it to be laterally adj usted.

From the upper portion of the standard or bracket E project the supports 2, that serve to retain thecup D in position, the supports 2 being furnished with slots 3, in which move the pin 4, projecting from the lower portion of the cup D, and the stem of the feed cup or reservoir 6, that is mounted upon top of the lubricant-cup D, and by preference these slots 3 are formed as open slots in order to permit the ready attachment of the lubricant-cup to the standard.

That part of the cup D in front of the guide A is formed as a hollow casting adapted to receive a suitable packing-such, for example, as asbestus, cotton-seed, or the liketo distribute the oil or other lubricating material upon the face of the guide A, and in the front of this cup is formed a suitable opening d, throughwhich the material within the cup may be forced against the face of the guide. The cup D is also provided with bifurcations or projecting portions cZ, adapted to overlap or straddle the guide A, in order to hold the cup in proper working position with respect to the guide, and to aid in distributing the lubricant upon the sides of the guide. By preference the bifurcations or projections d of the cup are made each with the inclined outer edges 4, in order to better distribute the oil upon the sides of the guide. These pro- `jections d are preferably simple solid extensions of the casting, as thin and light as is thatv overlaps 'or straddles the .guide shall be" the main cup,preferably behind the follower D', that is adjustable by means of the screws d3 and serves to force the asbestus D2 or other vehicle for lubricant forward slightly through the opening CZ in the front of the cup. A channel 8 is also formed in the top plate of the cup, and by preference connects with the channel 7, and serves to convey the excess of oil when the space behind the follower D is full to the front of the cup, whence it will iow upon the face of the guide A and the packing D2.

At the top of the standard E is pivoted the weighted lever G, one end of which bears against the back plate of the cup D and serves to force this cup normally forward, so as to cause the packing of asbestus or like material carrying the lubricant to bear snugly against the face of the guide A. At the same time the cup, being movabl)T sustained upon the bracket, will be allowed sufficient motion to 'compensate for the lateral play of the elevator.

In the form of my invention illustrated in Figs. 4t and 5 of the drawings t-he cup or holder D is shown as sustained in a manner permitting it to be laterally adj usted with respect to the elevator-guides, and in addition to this-adjustment the cup is provided with means whereby it can be adjusted back and forth with respect to the guide and can be held in desired position after such adjustment. This back-and-forth and lateral adj ustment of the cup is preferably secured by vproviding-the base 10 of the cup with long slots 11, through which will pass the bolts 12, that serve to hold the cup in position upon the cross-beam, the slots 1 1 allowing for the back-and-forth adjustment of the cup, while the slots 13, that are formed in the base-plate 14, enable the lateral movement of the cup to be effected. In this form of my invention, as in that hereinbefore described, the top plate of the cup D (which may be formed separate from the body and bolted thereto, as shown) is provided with the channels 7 and 8, corresponding to the channels in the top plate of the construction above described, and in like manner also the cup has projecting portions d', that overlap or straddle the guideA and serve to hold the cup in position with respect to the guide and at the same time aid in distributing the oil over the sides of the guide. In this modified construction, however, the follower D within the cup D is forced forward by means of a spring 20, that bears upon the follower, and also against a screw-cap 21 of the extension 22, formed on the back plate of the cup, thefollower being by preference furnished with a tubular extension 24, that insures its proper movement within the extension 22 of the cup. My purpose in thus providing the follower with means whereby it may exert a constant pressure upon the packing D2 is to insure the bearing of this packing against the face of t-he guide A, and when this construction is einployed it will not be found necessary to movably sustain the entire body of the cup, since the pressure of the follower upon the packing will cause it to protrude a sufficient distance to insure its bearing against thexface of the guide and compensate for the lateral'.

play of the elevator.

Instead of a spring for causing the follower D to press forward the packing'D2 against the face of the guide A, a weightmay be used for this purpose, and in Fig. 6 Ihave shown the follower D as provided with a stem 30, pressed normally inward by one end of a lever 31, that is pivoted, as at 32, to an extension on the back plate of the cup D, the

opposite end of this lever being provided with aweight 33, which serves to impart the desired pressure to the follower.

lubricator-cup may be provided upon its side` faces with openings throu gli which thepacking will be forced against the sides of the guide,

and in such case a follower will be used back of each of these side openings for holding the packing against each side face of the guide.

Having thus described my invention, what I claim as new, and desire to secure by YLetters Patent, is-- 1. The combination, with an elevator and its guides, of a guide-lubricator comprisinga cup or holder for the lubricant, and means whereby said cup or holder is sustained in manner permitting it to be laterallyadj usted with respect to the guides, substantially as described.

2. An elevator-guide lubricator comprising a. cup or holder for the lubricant, having an opening in its face and having a channel'for delivering oil to the front of the cup, substantially as described. f

3. An elevator-guide'lubricator comprising a cup or holder for the lubricant, having inits upper portion a channel leading from back to front and a channel leading into the back of the cup, and an oil feed-cup communicating with both of said channels, substantially as described.
